Transcription

1 Environmental Restoration in Harbor and Port Areas John Scandura, Branch Chief California Dept. of Toxic Substances Control Brownfields & Environmental Restoration Program Cypress, California

2 California Department of Toxic Substances Control One of six agencies within Cal/EPA Hazardous waste and substance regulatory agency Mission - protect California s people and environment from harmful effects of toxic substances by restoring contaminated resources enforcing hazardous waste laws reducing hazardous waste generation encouraging manufacture of chemically safer products.

3 DTSC Programs Hazardous Waste Management Program Authorized by U.S. EPA to enforce RCRA Permits hazardous waste facilities Inspections and enforcement action Manifest tracking Waste minimization Coordination with local Certified Unified Program Agencies (CUPA)

4 DTSC Programs Safer Consumer Products and Workplaces Program Enforces Safer Consumer Products legislation Prioritizes products, evaluates alternatives, and specifies reduction of chemicals of concern. Brownfields & Environmental Restoration Program Oversee remediation of hazardous substance release sites impacting human health and environment Expends state funds to abate threats where responsible party is non-viable or uncooperative

5 DTSC Brownfields & Environmental Response Program 1071 Active sites handled by four regional offices Permitted hazardous waste facilities Responsible party lead sites Military facilities Legacy landfills NPL sites School sites Brownfields sites Certified 1003 remediation projects as complete

6 Site Remediation Process Initial Assessment Site Characterization Nature and extent of contamination Risk assessment Identify applicable laws and regulations Alternatives Evaluation Remedy Selection Public review and comment CEQA compliance Remedy Implementation Remedy Certification Long Term Stewardship (if necessary)

7 Lead Agencies for Site Remediation U.S. EPA sites on National Priorities List only DTSC hazardous substance releases Regional Water Quality Control Board Groundwater impacts Petroleum hydrocarbons Tank Remediation Local CUPA Small sites, limited contamination Complex sites, multi-media contamination if has Tier II CUPA authorization

8 Regulatory Support Agencies Land AQMD/APCD air quality requirements CALTRANS transport of hazardous substances CA Fish & Wildlife sensitive habitats Regional Water Quality Control Board waste discharge requirements DTSC hazardous waste management Local agencies zoning requirements, local permits CA Dept. of Public Health radioactive substances

9 Regulatory Support Agencies Water AQMD/APCD air quality requirements CALTRANS transport of hazardous substances Coastal Commission permits, local coastal plan CA Fish & Wildlife sensitive habitats U.S. Fish & Wildlife federally protected species and habitats Regional Water Quality Control Board waste discharge requirements, dredge requirements Army Corps of Engineers dredge permits U.S. EPA NPL sites, dredge permits, Clean Water Act Ports, local agencies zoning, local permits

10 Common Issues in Marine Remediation Projects Administrative Multiple agency requirements, requires extensive coordination Coordination with port authorities CEQA analysis does not begin until remedy proposal emerges Sensitivity for communities, environmental advocates

11 Common Issues in Marine Remediation Projects Investigation Defining extent of contamination in sediments Presence of sensitive habitats and species Ecological risk assessment different from human health risk assessment Potential UXO near military installations

12 Common Issues in Marine Remediation Projects Implementation Limited alternatives for treatment and disposal of contaminated sediments Adequacy of sediment caps Transport of contaminated substances Air quality impacts Impact on sensitive environments Long Term Monitoring and Controls

13 Site Remediation in Marine Environments

14 Former Long Beach Naval Station and Shipyard 14 Installation Restoration Sites Closed in 1994 (Station) and 1997 (Shipyard) 303 acres transferred to Ports of L.A. and Long Beach West Basin remediated by Port of Long Beach

15 Long Beach Naval Complex Cleanup

16 Other Projects in Port of Long Beach TCL Port of Long Beach Current operation: Marine terminal Historic operation: Oil Production field Size: 240 Acres Contaminants: Petroleum hydrocarbons from oil production Toyota Port of Long Beach Current operation: Car storage Historic operation: Same oil production field as TCL Size: 31 Acres Contaminants: Petroleum hydrocarbons from oil production and disposal sumps

17 Port of Long Beach Projects Pier A/Area 2 Port of Long Beach Current and historic operation: Oil Production Size : 123 Acres Hazardous materials disposed 1965 to 1970, including drilling mud, tank bottoms, heavy metals, solvents, caustics, acids, sludge, and spent catalysts. 19 sumps remediated in 2008 Westway Pier J Port of Long Beach Current operation: Parking and storage area Historic operation: Solvent storage area and chemical facility Size: About 5 Acres Contaminants include semi-volatile organics and heavy metals. Site capped and groundwater monitoring ongoing

18 Port of Long Beach Projects Pier A TCL Terminal

19 Port of Los Angeles Sites Southwest Marine Ship building and repair, other port activities dating to Property currently vacant Remediation plan proposed Associated with Ports of Call revitalization. San Pedro Boat Works Boat refurbishing facility dating to 1923 Facility abandoned in 2002 Port of L.A. removed 1,500 tons sand blast waste, 127 lab-packed drums, 69 compressed gas cylinders,1 1 car/marine batteries in 2003 Remedial action plan under development

20 Port Hueneme Naval Base Small deep-draft military and commercial harbor. Deepened by Army Corp of Engineers to alleviate impacts of low tides. Sediments contaminated with PCBs, DDT and tributyltin in four areas. Contaminated sediments entombed in confined disposal cell covered by 10 ft. clean sand and 2 ft. rock to resist erosion from propeller wash and tidal actions.

21 Port Hueneme Naval Base Remediation Areas

22 Munitions Response Program Site 100 San Diego Bay Primary Ship Channel Munitions disposed into San Diego Bay during 20 th Century by Naval vessels prior to docking. Unexploded Ordnance (UXO), munitions found in dredged sediment used for beach replenishment. Small caliber munitions 81 mm projectiles Navy identified 90 potential or confirmed munitions areas Used side scan sonar, marine towed array magnetometer Further study narrowed investigation to 50 areas

24 Marine-towed Array (MTA) magnetometer Marine Sonic Technology High Definition Sonar side scan sonar system Transect guidance (via GPS) and DGM data recording equipment Side scan sonar data collection in primary ship channels.

26 Former San Diego Gas & Electric, South Bay Power Electric power generation facility on 158 acres fronting San Diego Bay in Chula Vista Began producing energy in 1960, operated until DTSC lead agency for investigation and remediation Dynegy performing demolition and debris removal Sempra performing remediation of historic contamination

27 SDG&E South Bay Power Plant - the Future Property owned by Port of San Diego Chula Vista Bayfront Master Plan Master-planned destination on 500-plus acres Hotels, convention facilities, homes, shops, restaurants 240 acres of parks and nature preserve Create 7,000 construction and 2,200 permanent jobs

28 Chula Vista Bay Master Plan

29 United States Coast Guard Aids to Navigation (ATON) Sites 198 Consent Order required Coast Guard to: Survey over 1500 California ATON sites for battery debris, Remove debris Determine extent of contamination, assess risks Implement corrective measures ATONs are lighted marine beacons powered by batteries. Historic ATONs powered by non-rechargeable batteries. Batteries used as early as 1918, used on large scale in 1960s. Replaced primary batteries with solar power panels and backup secondary batteries in early 1980s.

30 Coast Guard ATON Sites Survey found most sites underwater, long since disappeared Key disposal areas on Channel Islands Investigations and removals occurred on Santa Rosa, San Nicolas, San Clemente, Santa Barbara and Santa Catalina Islands completed in 2013.
